AIR-SHIP.

Specification of Letters Patent.

Application filed September 10, 1908. SerialNo. 452,379.

This invention resides primarily in animproved means to offset the reacting force in driving revoluble propellers, tending to revolve the car of an airship in areverse direction from that of the propellers rotation, more especially such propellers as serve to lift the car.

The purpose of the invention is to provide a casing surrounding the propeller and inconnection with the car, having means current generated by the propeller acts, tending to revolve the casing, and the car to which it is connected, in the same direction as the propeller, thus compensating for the reactionary'force developed in driving the propeller.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is an elevational View of an air-- ship embodying my improvements, the same being partly in central vertical section; and Fig. 2 is a cross-section through the ship substantially on the line 2-2 of- Fig. 1.

In the construction of my improved ship, I employ a car 5, of any suitable shape or character, to carry, in addition to the aviator," the means for supplying an actuating fluid to the motor, this means in the present embodiment consisting of a boiler 6 which is supplied with liquid fuel from the tanks 7 7, the latter being supported on a framework and arranged at each side of the boiler, on in any other manner preferred. The steam pipe from the boiler extends upwardly from its center and is provided with a valve 8 for controlling the passage of the steam to a motor 9, the casing of which is also carried by the steam pipe. The rotor of the motor withinthemotor casing is attached to a vertical shaft 10, which is journaled in the casing, and is provided thereabove with a propeller 11, the same being of well-known type. The shaft 10 is extended above the propeller and has a collar 12 journaled thereon between two fixed collars, the collar 12 being provided with ties 13 attached to the casing 14, which surrounds the propeller 11, .the motor casing 9, theboiler 6, andthe car 5. Below the propeller 11, the casing 1 1 hasa number of openings, over which are Patented Jan. 12, 1909.

placed at the outside, vanes or blades 15,

each blade being pivotally supported to swing outwardly from the casing, and having an extended portion 16 at the opposite side of its pivot, through which a bolt 17 eX-' tends for adjusting the blade to any desired inclination with respect to the casing 14,

.within certain limits. Below the blades 1'5,

the diameter of the casing is contracted by a conical portion 18, the casing being extended in true cylindrical form below the conical portion, in order to enforce the air passing from the propeller to leave the C357 ing in a vertical direction, this portion of the casing being preferably provided with inner spiral vanes 21 operating under the downward current of air from the propeller, to assist the vanes 15 in revolving the casing 'in the same direction.- I fixed to the motor casing 9 by a spider 19,

and is connected with the shaft 10 not only through the ties 13, but directly above the propeller by a spider 20, in which the shaft 10 is journaled.

In the operation of the ship, the steam is admitted to the motor 9, which is preferably of turbine construction, by opening the valve 8, causing the propeller to revolve in the direction indicated by the arrow in Fig. 2.

The air current generated by the propeller in moving downwardly is partially compressed by the contraction of the casing, and enforced to travel out through the openings in the side thereof impinging on the blades 15. The inclination of these blades relative to the direction of the rotation of the propeller is such as totend and thus overcome the reacting force of the steam on the motor casing 9 and prevent it and the car from revolving relatively to the earth. By adjusting the inclination of the blades 15, the required power tending to revolve the casing with the propeller tovex- The casing 14 isto revolve the casing in the same direction as the propeller actly neutralize reactionary force of the p motor, may be arrived at and in this manner no rotation of the car relatively to the r in the same propeller having amusing, and a casing s'urrounding the propeller and connected to the motor casing, having means actuated by the air from the propeller, tending to re volve both of said casings in the same direc.-. tion as the propeller.

3. The combination of a motor having a revoluble member and a non-revoluble member, a shaft fixed to the revoluble member and journaled in the non-revoluble member, a propeller secured to the shaft, and a casing surrounding the propeller and secured to the non-revolublemember of the motor,

having means actuated by the'current of air generated by the propeller, tending to revolve it in the same direction as the propeller.

4. The combination of a propeller, a casing surrounding the pro eller having an opening in the side thereo and a blade carried by the casing and arranged over said opening, inclining outwardly from the casing in a direction reverse to the revolution of the propeller. V V

5. The combination of a propeller, a casmg surrounding the propeller, having means at the outside thereof and means at the inside thereof tending, under the current of air from the propeller, to revolve the casing direction as the propeller.

6. The combination of a propeller, a casing surrounding the propeller, having an opening in the 7 side thereof, a blade overlymg said opening and inclining outwardly from the casing, and means for adjusting the inclination-of the blade.

7. The combination of a propeller, a casing surrounding the propeller, having a contracted lower portion and provided with openings above said contracted portion, and blades carried by the casing andoverlying said openings tending to drive the casing under the influence of the air from the r0- p'eller in the same direction as the prope ler.

8. The combination of a propeller, a cas' ing through which the current of air generated by the propeller passes,'and having an opening in the side thereof, and a blade overlying said opening, inclining in a direction to tend to rotate the casing under the influence of said current, in the same direction j as the propeller.

9. The combination of a shaft, a propellel. fixed to the shaft, a motor having a rotor connected to the shaft, a casing throu h which the current of air generated by t e propeller passes, attached to the motor casing, and means carried by the casing, 0 erated by the air current fromthe prope ler,

tending to revolve said casing and motor casing in the same direction as the propeller. 10. The combination of a car, a steam boiler carried by the car, having an upright steam pipe, a turbine motor carried by said, pipe, a shaft connected with the rotor of the motor, a propeller carried by the shaft, a casing surrounding the propeller and secured to a'fixed portion of the motor and provided with openings in the sidethereof, blades carried by the casing, overlying said openings and inclining in a direction to tend to revolve the casing in the same direction as the propeller under the influence of the current of air generated by thepropeller and passing through said openings.

In testimony whereof I have signed my '90 WILLIAM RUMBLE.
